STOVE.

Application filed .Tune 24, 1922.

To all whom it may concern:

Be it known that I, SoLoN l Massey, a citizen of the United States. residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

My invention relates to stoves and is intended more particularly for burning sawdust or other finely divided fuel. and one object of the invention is to provide means whereby the fuel may be retained in compact form and the heat currents therefrom caused to circulate so as to be efficiently utilized. Another object of the invention is to provide means whereby excessive dryness in the heat given off by the stove will be prevented, and a still further object of the invention is to provide means whereby the fuel-containing member will be guided into its proper relation .to the outside casingwhile being inserted therein and which means will also constitute means for maintaining the fuelcontaining member in proper spaced relation to the casing and also as a deflector to effect tortuous circulation of the heat currents. These stated olJject-s and other objects which will incidently appear in the course of the following description, are attained in such an apparatus as is illustrated in the accompanying drawings, and the in vention resides in certain novel features which will be particularly pointed out in the claims following the description.

In the drawings Figure 1 is a perspective view of a stove embodying my present invention;

. Fig. 2 is a vertical diametrical section of the same;

Fig. 3 is a horizontal section on the line 33 of Fig. 2;

4 is a horizontal section on the line i-et of Fig. 2; 1

Fig. 5 is a detail section through the fuelcontaining member or hopper showing the fuel compressing and shaping core therein;

Fig. 6 is a detail perspective view of the upper horizontal partition or deflector.

In carrying out my invention, I employ a base 1 which may conveniently be supported upon feet 2 of any approved pattern whereby thebase will be held in spaced relation to the floor or other fixed support. This base is provided with a door 3 to facilitate the insertion or removal of an ash pan 1 Serial No. 570,554.

and the said door will preferably be provided with a damper-controlled draft opening a.

The top of the base at is open, as clearly shown in Fig. 2, and is provided internally with an annular shoulder or flange 6 to receive and support the outer casing or drum 7. Below the shoulder or flange 6, an annular trough S is provided internally in the base which trough is adapted to contain a quantity of water. as indicated at 9, and through the upper portion of the base is provided a filling nozzle 10 through which the said water may be poured into the trough. The central open portion of the trough is preferably disposed concentric with the base immediately over the ash pan 1- so that the ashes falling through the outer casing or drum will be caught in the ash par: and may be easily and conveniently remover.

The casing or drum 7 is preferably cylindrical and may be of sheet metal, the lower end of the drum. being closed by a bottom plate 11. having a central opening 12 through hieh the ashes may drop but the upper end of the drum is open, as shown at 12, and around the upper end of the casing, l secure thereto a head or heat chamber 13, the top i l of which is removable and is constructed centrally to receive a lid or stove plate 15 of the usual form. The said stove plate or lid is supported by having its edge rest upon a shoulder 16 formed around the central opening of the cover 14 and the cover is in turn supported upon the annular wall of the chamber 13 by having its edge rest thereon. an annular head or flange 17 being formed on the under side of the cover to engage the annular wall of the heat chamber and thereby cause the cover to be n-operly positioned thereon. In the vertical annular wall of the top or heat chamber 13 are provided openings 18 and 19 through .vhich the products of combustion and spent heat currents may flow and these openings are alternately inlet and outlet openings according to the disposition of dampers 20 and 21. the said dampers being contained within lines 22 and 23 respectively. which have their ends fitted about the flanges 24: and 25 formed around and defining the openings 18 and 19, as clearly shown in Fig. 2. The lines 22 and 23 lead into an escape pipe 26 which may pass to a chimney or in any other manner communicate with the outside air so as to carry off all obnoxious fumes and waste products and the lower end of the said escape pipe 26 is disposed below the lower flue 23 and equipped with a check damper, indicated at 27, which may be of any approved type. [is shown in Figs. 1 and 2, the lines 22 and are arranged in superposed relation and within the top or heat chamber 13 is provided a horizontal partition or deflector 28, the said partition being of the areuate form shown most clearly in Fig. 6 and supported on the bottom of the head 13 by depending feet 99 which are disposed parallel to a radius of the heat chamber with their inner surfaces flush with one wall of guiding grooves 30 provided in the wall of the casing or drum 7. The said grooves 30 may conveniently be formed by pressing from the. wall of the casing or drum offsets or ribs 31 at diametrically opposite points of the drum, and these offsets terminate short of the bottom of the casing. I also provide on the annular wall of the heat chamber, at a point diametrically opposite the partition 8, a deflecting rib which extends approximately half way around the said. annular wall and is located in a horizontal plane above the plane of the partition 93. The deflector 32 is of less width than the heat chamber so that it will not interfere in any way with the insertion or removal of the fuel-containing member or hopper 33. The said fuel-containing member or hopper is preferably of sheet metal and is in the form of acup or cylindrical receptacle having an opening 34. in its bottom adapted to register with the opening 12 in the bottom of the drum when the parts are assembled. The hopper is provided externally at diametrically opposite points with ribs or wings 35 which are adapted to enter the grooves 30 of the drum and thereby guide the hopper while it is being inserted or removed and upon reference to 3 and 41: particularly, it will be noted that the diameter of the hopper is appreciably less than the diameter of the drum so that an annular circulating space will be provided between the drum and the hopper. The ribs or wings 35 bridge thesaid circulating space,-

as shown clearly in Fists. 3 and 4:, and said wings or ribs terminate short of the lower end. of the hopper so that, when the lower ends of the ribs rest upon the lower ends of the grooves, the top of the hopper will. be flush with the partition 28, as shown clearly in Fig. 2. The ribs, consequently. aid in supporting the hopper within the drum and also constitute guides for the hopper while it is being inserted or removed and also constitute baffles for the heat currents, as will presently more fully appear. The hopper is further provided externally with a spiral rib or baffle 36 which further retards the heated currents so that the heat given oil by the same may be fully utilized.

As herein previously stated, the device is intended more particularly for consuming .awdust or other finely divided fuel. In order that the said fuel may be in a compact form. within the hopper, l provlde a core 37 which is preferably a tapered cylindrical plug having its lower end adapted to fit snugly in the opening 34- in the bottom of the hopper and of such length that its upper end, which may be equipped with a handle 38, will project above the upper end of the hopper. in the use of the device, the cover 14 is removed and the hopper withdrawn. The core or plug 37 is inserted in the hopper and the fuel, indicated 39, which may be slightened moistened, if preferred, is placed in the hopper around the plug, as shown in Fin. 5, so that it may be arranged compactly within the hopper and will have a central draft opening); 40 therethrough when the plug or core is withdrawn. After the hopper has been filled, the core is removed and the hopper then inserted downwardly into the drum or casing, after which the cover 14 is restored in position over the upper heat chamber In placing the hopper within the drum, the ribs or wings 35 thereon are caused to aline with the grooves 30 in the drum and the hopper may then be permitted to descend within the drum without thought as to its ultimate position inasmuch as the engagement of the said ribs or wings with the grooves will. effectually and positively guide it into iis proper place. It will be readily noted that the inner arcuate edge of the partition 28 will abut the hopper at the upper end thereof so that the heat chamber will be divided into two compartments separated by the upper end of the hopper and the partition 28 with its feet 29 which abut the upper extremities of the ribs or wings 35. In starting a fire within the stove the door 3 is opened and a match or other igniting instrumentality is passed through the door opening and the base so as to reach the fuel through the openings 12 and 3a. Initially, the damper 20 will be set in open position and the damper 21 in closed position so that a direct draft will be permitted through the center of the body of fuel and the fine 22. After complete combustion is developed, the damper 20 is closed and the damper 21 opened, as shown in Fig. 2, whereupon the draft through the flue 22 will be cut off and the products of combustion and the heat currents arising" from the fuel will be retained within the chamber 13, except as they are turned downwardly by the deflector 32 and caused to pass into the space between the drum and the hopper at one side of the ribs or wings 35. The said currents. will conse- .be readily quently be caused ,to flow downwardly between the drum and the hopper until they reach the space below the lower ends of the ribs 35, whereupon they may flow beneath. said ribs and then rise through the space between the drum and the hopper to the compartment below the partition 28, and thence flow out through the flue 23. A tortuous circulation of the heat currents between the hopper and the drum so that the wall of the drum will be thoroughly heated and will throw off heat into the room in which the stove may be placed, and this tortuous circulation of the heat currents will be increased by the spiral battle 86 upon the hopper, 0

ll stove is obviously very simple in its construction and may be produced at a very low cost. ictual experience has shown that a single charge of fuel will last for a prolonged period and effectually heat the room in which the stove may be located, and it will noted that inasmuch as the hopper is easily removed, a filled hopper may be substituted for a hopper in which the fuel has been consumed very easily and quickly. If it should be inexpedient to provide a plu rality of hoppers to be interchangeably used, it will be a very simple matter to insert the core 37 in a-hopper which is already in position in the stove and fill fuel into the hopper and around the core through the heat chamber 13.

Having thus described is claimed as new is:

1. In a stove, the combination of a drum, a hopper rcmovably fitted within the drum, diametrically opposite ribs upon the hopper constituting baffles between the hopper and the drum and maintaining the hopper in spaced relation to the drum, said ribs terminating short of the lower end of the hopper, upper and lower flues extending from the drum, and a horizontal partition within the drum extending from the wall of the drum the invention, what is thus set up at a point between said flues to the ribs on the hopper.

2. In a stove, the combination of a drum, an expanded heat chamber at the upper end of the drum, a hopper reinovably fitted in the drum with its upper end extending into said heat chamber, ribs on the hopper ex tending therefrom to the drum and terminatshort of the lower end of the hopper, a horizontal partition within the heat chamber leadingfrom the vertical wall thereof to the ribs on the hopper and abutting the upper end of the hopper, flues extending from the said vertical wall of the heat chamber above and below said horizontal partition, and draft-regulating dampers within said fiues.

In a stove, the combination of a drum, a, hopper disposed concentrically within the drum in spaced relation thereto and projecting above the upper end of the drum, a heat chamber carried by the upper end of the drum and surroundin the upper end of the hopper, a horizontal partition leading from the side of the heat chamber to the top of the hopper at one side of said heat chamher, a deflector at the opposite side of the heat chamber above the hopper, and draft controlling means connected with the said heat chamber.

In a stove, the combination of a base, an annular trough within the base, means for permitting the feeding of water into said trough, a draft door in the base below the said trough, a drum supported on the base and having an opening through its bottom communicating with the base, a hopper removably fitted in the drum in spaced relation thereto and. provided in its bottom with an opening registering with the opening in the bottom of the drum, and means for con trolling circulation through and around the hopper.

In testimony whereof I affix my signature.
